Bifidobacterium plantarum and Improved Immune Modulation

Research synthesisVery low evidenceModerate effect3 studies · 3 beneficial · 0 neutral · 0 harmful

Across all 3 available studies (all beneficial), moderate-sized effects on immune modulation are reported. However, the evidence base is comprised entirely of narrative reviews that do not report participant-level data, doses, or conventional significance testing. No specific dose range or population can be identified from this evidence.

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. All three studies are general reviews rather than original trials, meaning the findings are indirect and lack controlled experimental data on Bifidobacterium plantarum specifically. No information on doses, durations, or statistical significance is available. Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed).
